[W126 Coupe] Long term Problem

[Mister McGoo]

Vance;

The only fuse menu I have is for the 1986 and lists #8 fuse (16amp) for 
"Outside Heater mirror, Seat Belt extensioners, Anti-theft Alarm System, 
Rear Cigar lighter".  Maybe it was an early model when smoking cigars (in 
the rear) was still legal.

It also lists (in the same fuse box) in Relay "K" - "Auxiliary Fuse Holder 
(Anti-theft Alarm System)".

Check with your fusebox to confirm.  I imagine yours is the same as the one 
(1991) that Dan attached.  Perhaps Dan can confirm the relay layout also.

Assuming that your after-market alarm system may have taken power from the 
same source, check to see if removing this (these?) would disable the alarm 
system's power and if so, then test for the intermittent power draws again.  
That may confirm if the alarm system (or wiring) is the culprit.

The only thing that makes the alarm system suspect is the fact that the four 
way flashers came on when the mysterious 6 amp draw occurred.  I understand 
that even that is not consistent, right?

I suggested that only because it is very simple to check.

Likely the 1 amp fuse trick would identify which circuit is at fault.  Have 
you tried that yet?  Have you found (made?) 1 amp fuses?
